Crankcase Breather Mini Filter

The mini air filter breather is used on the cylinder head to filter exhaust gases emitted from the PCV valve, reducing air pollution while preventing oil vapor from flowing back into the throttle body and preventing carbon buildup in the combustion chamber. When used on the intake pipe, it can create a secondary air intake effect to increase horsepower. It is easy to install and suitable for various soft or hard hoses.

Established in 1991, SIMOTA specializes in high-flow air filter designs for motorsports and is an ISO9001-certified manufacturer and supplier. It has also obtained strict TUV product certification in the automotive industry. SIMOTA has consistently maintained the most advanced innovation in intake systems and is firmly committed to pursuing higher standards.
